So why did Hampnie kill all the villagers, and why didnt Ai stay pissed at him ...
I think he killed everyone because he wanted to destroy everything that reminded him of his wife, she was the founder of that village. She created that village so that the people who were already dead could continue living normally. (They were already dead). She basically tried to create a mini version of that place where people were killed and wore masks and stuff. (It's been a while since I watched it so I forgot the name of the place).
I also believe that he wanted them to live happily, and I don't believe they were doing that as they were. They were slowly starting to turn 'greedy' as described by Hampnie. Part is he hates the living dead because it goes against the nature of what God had wanted; the dead should remain dead. But I also believe it is mercy for those that are already dead and those living around them. To live and go mad, never to find peace is a sad way to live. As for those living, to watch your loved ones and friends go mad and there is nothing you can do, is just as sad.
But one thing that Orange does say that I don't agree with is he wants to destroy everything that reminds him of Hana. I believe that he has lived in the world where he has become cynical and with no more God, he had to become his own moral compass. He set his morals and he runs on them. There is also the fact that he was not aware that, that little compound they were living on was created or designed by Hana. All he knew was that those people were already dead. Except for possibly Youki, who supposedly committed suicide after Hampnie killed Anna.
What do you think?
